Hi. love the plugin, really handy.
I've used the plugin in a newly launched entertainment news website and have run into a couple of bugs.
The first and most pressing is that it doesn't seem to work for JPG images. When you load the modal window to select the thumbnails the original image on the left and all the different sizes on the right don't load the image, (little broken image signal appears). I think it may have been working at SOME point for jpgs, but certainly not anymore. PNGs are fine however.
The second issue might be less of a bug and more of a suggestion: as we post many posts to the same category, we'd like to be able to reuse the same image from the media library and have the thumbnails we have already created carry over to the new posts. Is this possible? At the moment it seems like the editor has to reselect the thumbnail areas each time, and as we have 3 different sizes we cater for this can quickly become repetitive.
Once again, even with the bugs the plugin has proved to be a vital tool, so thanks for all the work you've put in so far!
